SELF-FEEDING OPEN-FIREPLACE GRATE.

SPECIFICATION forming part of Letters Patent No. 496,326, dated April25, 1893.

' Application filed January 30,1892. Renewed March 31, 1893- Serial No.468,575. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH WILLIAM SHAW, of the city of Chicago, countyof Cook, State of Illinois, have invented certain new and usefulImprovements in Self-Feeding Open-Fireplace Grates, of which thefollowing is a specification.

Myinvention provides ameans of making an open fire place self feeding aswell as an im provement in the blower of said fireplace by which saidblower is made adjustable.

The objects of my invention are: first to provide a means by which anopen fire place may be made self-feeding; second to provide a directdraft when the blower is in position and third to provide a means ofhaving an adjustable blower.

My invention is illustrated by means of the accompanying drawings inwhich Figure l is a front elevation of the fireplace with the blowerdown. Fig. 2 is a section through Fig. 1 on line w-a: showing the blowerin section when it is down. Fig. 3 is a front elevation of said fireplace with the blower open.. Fig. 4. is a section on the line yy of Fig.3 showing the blower in section when it is open. Fig. 5 is a rear viewof the fire place showing the coal magazine and draft opening inelevation. Fig. 6 is a perspective of fireplace with the blower back andcovering the draft opening also showing the grate in position with thegrate front removed.

Similar letters referto similar parts throughout the several views.

Inclosing the open fire place is the iron casing E which passes from thefront piece H around the back of said fire place. Above this plate isthedeflecting plate F which joins onto the angular plate S said angularplate having in it the direct draft openingD all of which are shown inthe sectional views Figs. 2 and 4. The grate C, grate front a and draftplate cl may be of any approved pattern or design. The blower is made intwo parts A and A which are connected by means of a hinge. The upperpart of the blower A fits close to the side of the niche E and is madeto swing by means of a small projection on the top A which projectionextends over and fits into a small recessin the top of the side plate E.Connected with this upper plate come the Weight of said lower blowerplate.

These weights A are cast on the lower blower plate A in such a mannerthat when said lower blower plate is down the weights will be closeagainst the upper blower plate A as will be seen by reference to Fig. 2.By this means said plates will not act to throw the lower blower plateup when said plate is in a vertical position but as soon as it is thrownout of a vertical line or the blower is pushed 1 back then the weightswill cause said lower blower plate to throw up against the upper blowerplate as will be clearly seen by reference to Fig. 4. which shows saidplates thrown back. The lower plate is made so as to clear the frontplate H. In the upper blower plate is a set of check drafts 6 made ofany approved form or design.

In the upper part of the front plate H is placed the feed door B whichopens into the neck B of the magazine B said magazine being used as areceptacle for coal by which means the fireplace is made self feeding.This magazine consists of the neck B and the main part B; the neck beingconnected at the upper part with the front plate H and having in it thefeed door B while the main part B is connected with the deflecting plateF by means of small projections or bosses. on said deflecting platemaking a socket for it to set in as will be seen by reference to thesectional views Figs. 2 and 4. Connected with said deflecting plate andcast to it is a continuation of the main part of the magazine whichextends downward into the opening of the niche of the fireplace as willbe seen in Figs. 2 and 4.. In using this fireplace with its attachmentsthe fire is first built of wood and a small amount of coal; both partsof the blower are placed down as is represented in Figs. 1 and 2 and thedraft in the draft plate d is opened while the check draft e in theupper blower plate is closed. By this means a draft passes up throughthe fireand 0E through the draft opening D in the angular plate S.

IOO

soon as the fire is started coal is put into the fireplace by means ofthe feed door 13 the magazine and its'neck, the blower plates beingdown, enough coal being put in to fill the fire-place up to theprojection 13 of said magazine after which enough is put in to fill themagazine and neck. In this way as fast as the coal is burned away fromthe projection B'it will be replaced by the coal moving down in themagazine and neck I3, I3 When the fire is well burned up the upperblower is pushed back by means of the rodfso that it closes the draftopening D and the lower blower plate being thus moved from a verticalline is immediately moved up against the upper blower plate by means ofthe Weights A heretofore described. When the blower is placed in thisposition the check drafts e are opened while the drafts in the draftplate (Z are closed. By this arrangement the fire may be made to burnopen and without a draft. \Vhen it is desired to have the fire burn morefreely the blower is again closed while the blower drafts are opened andthe check drafts closed being the same position as when starting thefire and illustrated by Figs. 1 and 2.

Having thus described my improvements,

What- I desire to claim as my invention and to secure by Letters Patentis-- 1. An open fire place composed of the double blower A, A operatedas described, the check draft e, the direct draft opening D, thedeflecting plate F, the feed magazine 13, B and the extension tip B incombination with the grate, sides and back substantially as described.

2. In an open fire place the hinged blower A A suspended from the sidepiece E and arranged to operate by means of the rod f the weights A andthe front piece H substantially as described.

3. In an open fire place the combination of the side and back plates,the angular plateS having in it the direct draft opening D with theblower A A suspended from said side plates and the check draft 6 in saidblower all substantially as and for the use set forth.

4. In an open fire place the combination of the magazine B B with thedeflecting plate F and the extension tip B all as and for the usedescribed.
